Advise....R U N, habang may time ka pa. The way I see it, kung dito pa lang 8 out of 10 comments swaying at the Negative side, eh halos LANSHOP owners yata ang nag comment na, that tells you something na di ba. Of course wala rin makapigil sa iyo kung gusto mo talaga, pero don't say din na they did not warn you of the things that you need to face when you start a new business.
Looking at your proposed business area, and as you said hindi ka naman uupa na, less expense TRUE, but that is a misconception. You should always take it into account that this place could also be a potential income generating place, meaning, if you think that it can be rented at 5k, then take that into consideration because it helps you in your decision making kung let's say parentahan na lang ng 5k or trabahuin ko at kikita ka lang ng 5k(hypothetically). Then the answer is obvious right?
Syempre walang katumbas na pera ang kasama ang pamilya, so think of the trade-off din.
Computer shop business, there are so many things to consider and decide at any given time, if you haven't been in any business before and much more if you do not know much about computer shops ( I mean shops not just computer per se), then ask my opinion...I say DON'T DO IT. Consider something else let's say LUGAWAN, you may laugh but it's true. Mas may kikitain ka diyan kaysa Lanshops. Just myy two cents
